Hollow pumping silicone light strip

by:Kenna     2021-04-25
Hollow pumped silicone light strips, energy-saving doors and windows are roughly composed of profiles, hardware, glass and EPDM door and window sealing strips, and several major modules of processing technology. The sealing strips have a lower cost due to their proportion, and some do not pay attention to energy-saving doors and windows. The influence of the traditional concept of standards has been ignored by many door and window manufacturers, but we cannot but admit that the sealing strip plays a vital role in the door and window system. What important role can the EPDM sealing strip play in the door and window system? What? . Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. Because PVC products contain halogens and heavy metals in stabilizers, they are not conducive to environmental protection. Therefore, developed overseas and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips, which are flexible at low temperatures and have a tensile capacity of 100MPa. The temperature is -58. EPDM is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene. The international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. According to the cross-sectional shape, it can be divided into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips The cross-section design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. According to the sealing characteristics, they can be divided into weather seals. Strip (WEATHERSTRIP) and general sealing strip (SEALING). The lip length and thickness should be appropriate. Too thick or too long will increase the resistance of the glass to lift. Too thin or too short will cause the glass to not be well guided and sealed, resulting in vibration, noise, and rain leakage; the second is The shape and size of the bottom of the section are designed. There are protrusions on the section of the window steel channel, which is used to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can utilize the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; it is the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely attached to the body. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety.

Ensure personal safety. The hollow-pumped silicone light strip is one of the important parts of the automobile. It is one of the important parts that determine the quality of the automobile. What are its more important roles in the automobile? Bubble sealing strip 1. The basic concept of mechanical seal: mechanical seal means that at least a pair of end faces perpendicular to the axis of rotation are kept close to and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal. And constitute a device to prevent fluid leakage. A small number of door and window companies in low-level price competition are still in use. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used in the manufacture of airplanes and cars. , Trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties
